      Don't build extra object with -no-hs-main · a01e78cc
      Sylvain Henry authored
      We don't need to compile/link an additional empty C file when it is not
      This patch may also fix #18938 by avoiding trying to lookup the RTS unit
      when there is none (yet) in the unit database.

      Make sure HasField use counts for -Wunused-top-binds · 1109896c
      Adam Gundry authored
      This is a small fix that depends on the previous commit, because it
      corrected the rnExpr free variable calculation for HsVars which refer
      to ambiguous fields. Fixes #19213.

      Implement NoFieldSelectors extension (ghc-proposals 160) · 2521b041
      Adam Gundry authored
      Fixes #5972. This adds an extension NoFieldSelectors to disable the generation
      of selector functions corresponding to record fields.  When this extension is
      enabled, record field selectors are not accessible as functions, but users are
      still able to use them for record construction, pattern matching and updates.
      See Note [NoFieldSelectors] in GHC.Rename.Env for details.
      Defining the same field multiple times requires the DuplicateRecordFields
      extension to be enabled, even when NoFieldSelectors is in use.
      Along the way, this fixes the use of non-imported DuplicateRecordFields in GHCi
      with -fimplicit-import-qualified (fixes #18729).
      Moreover, it extends DisambiguateRecordFields to ignore non-fields when looking
      up fields in record updates (fixes #18999), as described by
      Note [DisambiguateRecordFields for updates].
